ABSTRACT:
A muffler device for use in a brake booster system in which there are inserted in an air suction passage cylindrical noise shielding member having at one end an outer flanged portion extending radially outwardly and at the other end an inner flanged portion extending radially inwardly, the circumferential wall of the noise shielding means being defined with an air suction opening; and cylindrical noise absorbing member with a gas permeability being inserted into the inner circumference of the circumferential wall, in such a manner that noises as generated at the valve mechanism during the operation of the brake booster may effectively be prevented from propagating to the outside by aid of the noise shielding member and the noise absorbing member together.
